Question

In GIS, the stored information—either spatial data or associated tabular data—can be retrieved with the help of a language called:

• A. C language
• B. Python
• C. SQL
• D. FORTRAN

Hint:

GIS querying = SQL; used to retrieve tabular and spatial info.

Answer 1

The Correct Option is C

The question asks about the language used to retrieve stored information in GIS, which can be either spatial data or associated tabular data. The most common language used for querying databases in GIS is SQL (Structured Query Language).

SQL is a domain-specific language used in programming and managing data held in a relational database management system. It is particularly useful for handling structured data where relations between entities and variables are mapped out.

In the context of Geographic Information Systems, SQL enables users to perform various tasks such as:

• Retrieving data through queries.
• Filtering data based on specific criteria.
• Joining spatial data with tabular data.
• Returning datasets in a structured format.

Therefore, the correct answer to the provided options is SQL.
